A method for displaying a favorite channel in a device for receiving a broadcasting program includes presetting a favorite program viewing standard time; identifying whether a key signal is inputted by a user, displaying a broadcasting program received from a selected channel; detecting a viewing time of the program based on the inputted key signal; comparing the detected program viewing time with the preset viewing standard time; and registering the broadcasting program with a favorite program list based on the result of the comparison.

Description

TECHNICAL FIELD
The present invention relates to a device for receiving broadcasting programs. More specifically, the present invention relates to a device for receiving broadcasting programs which a user can register with a favorite channel list after viewing for a pre-determined time period, and a method for displaying a favorite channel by using the same.
BACKGROUND ART
Recently, accelerated digital broadcasting enables high definition and high quality sound broadcasting to start through a satellite, terrestrial and cable broadcasting system. Compared with a conventional analog television, a digital television may provide various additional services as well as high definition and high quality sound.
Such the digital television compresses high definition/high quality audio and video data (A/V data) by using A/V compression technology of MPEG-2 and AC-3 and transmits the compressed A/V to a user via a conventional satellite/terrestrial/cable band by using QPSK/VSB/QAM. As a result, various services can be supplied to a single channel.
A SD television may provide more than four channels of the terrestrial broadcasting with a conventional single channel and a HD television may provide one channel of the terrestrial broadcasting. Together with that, a digital television may transmit auxiliary information with A/V to provide various services. Thus, a kind of service such as a program guide for added channels may be supplied to the user.
Watching TV, the user may see information of the above program guide such as program titles, times, story lines and formats on a TV screen, which can be typically read on newspapers.
Moreover, because of the technology of A/V compression and the technology of transmission and compression, more channels can be broadcasted in the digital TV than in the analog TV. As a result, users should spend quite a time on finding channels that they want to see among the added channels.
As shown in FIG. 1, if the user registers only a favorite channel to a TV 10 and a key signal of a favorite channel is inputted via a user interface, a favorite channel list 30 set by the user is displayed in some portion of a screen 20 which is displaying a TV program such that the user may select the favorite channel conveniently.
DISCLOSURE OF INVENTION Technical Problem
However, according to the conventional favorite channel list, only the channels set by the user as favorite ones are listed and supplied on the screen. This causes inconvenience in that the user should register the favorite channel every time.
Moreover, only channel numbers of the favorite channels set by the user are displayed. As a result, the user cannot recognize which program is broadcasted on the corresponding favorite channel. To recognize that, the use should change the channel into the corresponding favorite channel and this is inconvenient.
Technical Solution
To solve the problems, a method for displaying a favorite channel in a device for receiving a broadcasting program includes presetting a favorite program viewing standard time; identifying whether a key signal is inputted by a user, displaying a broadcasting program received from a selected channel; detecting a viewing time of the program based on the inputted key signal; comparing the detected program viewing time with the preset viewing standard time; and registering the broadcasting program with a favorite program list based on the result of the comparison.
The key signal inputted by the user may be a channel change signal or a power off signal.
If the power off signal is inputted, a total viewing time of the program broadcasted at the present may be detected.
If the detected viewing time of the program is more than the preset viewing standard time based on the result of the comparison, the program may be registered with the favorite program list.
If the detected viewing time of the program is less than the preset viewing standard time based on the result of the comparison, the detected viewing time of the program may be deleted.
The method according to the present invention may further include displaying at least one program stored in the favorite program list at a user s request, together with a broadcasting time statue for each corresponding program of the favorite channel program list.
The information of the broadcasting time statue for each program may be displayed in a bar type, differentiating a color of a broadcasted time area from a color of a to-be-broadcasted time area.
If the user selects a specific program, detailed information of selected program may be provided.
If a confirmation key signal corresponding to the program of which detailed information is provided is inputted, a channel viewed at the present may be changed into a channel broadcasting the corresponding program.
If a delete key corresponding to the program of which the detailed information is provided is inputted, the corresponding program may be deleted from the favorite channel list.
A device for receiving a broadcasting program according to the present invention includes a tuner for receiving a broadcasting program of a selected channel at the present; a program viewing time detection unit for detecting a total viewing time of the received program; a memory unit for storing the detected viewing time of the program, a favorite program viewing standard time preset by a user and a favorite program list; a user interface for receiving a key signal from the user; and a control unit for comparing the total viewing time of the received program with the preset favorite program viewing standard time if the key signal is inputted via the user interface, the control unit for registering the received program with the favorite channel program list or deleting the viewing time of the corresponding program stored in the memory unit based on the result of the comparison.
The key signal inputted from the user interface may be a channel change signal or a power off signal.
If the power off signal is inputted by the user, the program viewing detection unit may detect a total viewing time of the received program at the present.
The memory unit may update the detected viewing time information of the program continuously until the power off signal is inputted.

The control unit 102 generally controls the TV. A user inputs a channel change signal or a power on/off signal via the user interface 104. In the memory unit 106 are memorized a favorite program viewing standard time set by the user, information of the channel viewing time and information of the channels registered as favorite channels. The tuner 100 performs tuning of broadcasting channels in accordance with the control of the control unit 102. The TS decoder 108 processes a digital broadcasting signal and the NT decoder 114 processes an analog broadcasting signal. The program viewing time detection unit 116 detects the viewing time of the program selected and viewed by the user. The A/V processing unit 120 processes broadcasting data provided by the digital or analog signal to be outputted via a speaker 122 and a displayer 124.
The control unit 102 controls the TV generally as mentioned above. Specifically, if a channel change signal or a power control signal is inputted via the user interface 104 according to the embodiment, the control unit 102 determines whether a program broadcasted at the present is viewed for more than the favorite program viewing standard time and it controls the program at the present to be registered with a favorite channel list based on the result of the determination.
In addition, if the signal inputted via the user interface 104 is a power off signal and the total viewing time of the program at the present is less than the favorite program viewing standard time, the control unit 102 deletes information of the program viewing time at the present which is memorized in the memory unit 106.
If a signal of requesting to display the list of programs stored in the memory unit 106 as favorite program, the control unit 102 displays the information of the program viewed at the present or the information of plural favorite channel programs broadcasted on the other channels at the present.
At this time, if a specific program is selected from the favorite channel list by the user, detail information of the selected broadcasting program is displayed. Hence, if a signal of channel change to the selected channel broadcasting the corresponding program is inputted and if a signal of deleting the selected program is inputted, the selected program is deleted from the favorite channel list.

The tuner 100 tunes the channels controlled by the control unit 102 out of broadcasting data inputted via the terrestrial or cable. Thus, the tuner 100 transmits digital signals received via the tuned channels to the TS decoder 108 for processing a digital broadcasting signal and analog signals received via the tuned channels to the NT decoder 114 for processing an analog signal.
Here, the tuner 100 receives a broadcasting program selected at the present and displays the program on the screen.
The TS decoder 108 decodes the digital signal supplied by the tuner 100 and it converts the digital signal into an A/V stream or a data stream to transmit the streams to a first switching unit 110.
The first switching unit 110 processes the A/V stream and the data stream into a broadcasting signal in accordance with the control of the control unit 102. Hence, the first switching unit 110 transmits the processed signal to the A/V processing unit 120 to output the broadcasting. In addition, the first switching unit 110 transmits auxiliary data included in the broadcasting program received via the tuner 100 to the program viewing time detecting unit 116.
A second switching unit 112 is further provided. The second switching unit 112 receives the analog broadcasting signal from the tuner 100 and an external input signal. Hence, the second switching unit 112 selects and transmits either of the two signals to the NT (STSC) decoder 114 in accordance with the control of the control unit 102.
The NT (NTSC) decoder 114 for processing the analog broadcasting signal receives the analog broadcasting signal or the external input signal from the second switching unit 112 to decode it into an audio and video data. Especially, in this embodiment, the NT decoder 114 transmits the auxiliary data included in the broadcasting program received from the tuner 100 to the program viewing time detection unit 116 in accordance with the control of the control unit 102.
The program viewing time detection unit 116 detects the total broadcasting time of the corresponding program and the viewing time of the corresponding program viewed by the user from the auxiliary data of the program received from the tuner 100. As a result, if the channel change signal or the power control signal is inputted by the user, the program viewing time detection unit 116 transmits either of the two signals to the control unit 102.
At this time, the control unit 102 determines whether the corresponding program is viewed as long as the favorite program viewing standard time, that is, whether the program is viewed for more than the preset favorite program viewing standard time out of the total program broadcasting time by using the information of the corresponding program transmitted by the program viewing time detection unit 116. Based on the result of the determination, the control unit 102 automatically registers the program viewed for more than the favorite program viewing standard time with the favorite channel list.
The A/V processing unit 120 processes the audio data and the video data of the program received from the first switching unit 112 such that the processed audio data is outputted to the speaker 122 and the video data is outputted to the display unit 124. In addition, the A/V processing unit 120 mixes an OSD data provided by the control unit 102 with the video data and it transmits the mixed data to the display unit 124.
Here, the OSD data displayed on the screen of the broadcasting receiver is the favorite channel list which is displayed at a predetermined area of the screen in a block type at a user'request. Such the favorite channel list is configured of a bar type including titles and broadcasting times of programs.
In addition, a specific program selected by the user from the favorite channel list is highlighted and detailed information of the selected program, that is, the highlighted program is displayed adjacent to the list of the programs.
